Transcriptional responses of Aedes aegypti chemosensory tissues in response to volatile DEET and citronella oil

Insect Molecular Biology, EarlyView.
Aedes aegypti females were significantly repelled by both volatile DEET and citronella oil in comparison to control (ethanol‐exposed) mosquitoes. Global gene expression changes were largest in the mosquito mouthparts, with notable downregulation of the three subunits comprising the mosquito CO2 receptor (Gr1, 2 and 3).

Functional morphology and sexual dimorphism of mouthparts of the short-faced scorpionfly Panorpodes kuandianensis (Mecoptera: Panorpodidae). [PDF]

PLoS ONE, 2013
Mouthparts are closely associated with the feeding behavior and feeding habits of insects. The features of mouthparts frequently provide important traits for evolutionary biologists and systematists.

First Zoeal Stage of the Snapping Shrimp Alpheus Fabricius, 1798 (Caridea: Alpheidae): New Description of Alpheus bouvieri A. Milne‐Edwards, 1878 and Literature Review

Acta Zoologica, Volume 107, Issue 3, Page 361-376, July 2026.
ABSTRACT Based on adult morphological characters, the more than 300 species of Alpheus were divided into seven informal species groups, but some groups are not supported by molecular data. The aim here was to describe the zoea I of Alpheus bouvieri, and to do a review of the larval descriptions available in the literature, analysing whether the ...

Identification and Expression Profile Analysis of Chemosensory Genes From the Antennal Transcriptome of Bamboo Locust (Ceracris kiangsu)

Frontiers in Physiology, 2020
Studies of chemosensory genes are key to a better understanding of intra- and interspecific communications between insects and their environment and provide opportunities for developing environmentally friendly pesticides to target pest species.

Unearthing Mesozoic beetles through micro‐computed tomography: A new family of Archostemata and the first representatives of Ommatidae and †Notocupes from the Crato Formation

Systematic Entomology, Volume 51, Issue 3, July‐September 2026.
First formally described Archostemata beetles from the Lower Cretaceous Crato Formation are reported, representing the earliest records of the suborder from western Gondwana. Micro‐computed tomography enabled three‐dimensional reconstruction of partially exposed fossils, revealing previously hidden dorsal and ventral morphological characters relevant ...

Molecular Insights and Repellent Efficacy of the Essential Oil and Major Compounds From Piper cyrtopodon (Miq.) C.DC (Piperaceae) Against Aedes aegypti (Linnaeus, 1762) (Culicidae)

Archiv der Pharmazie, Volume 359, Issue 6, June 2026.
The essential oil and major compounds from Piper cyrtopodon exhibit potent, long‐lasting repellent activity against Aedes aegypti mosquitoes, combined with low cytotoxicity and favorable molecular docking interactions with odorant‐binding proteins. These findings highlight its potential for the development of alternative products for bite prevention ...

Sensory Morphology of Geodorcus helmsi (Coleoptera: Lucanidae) and its Relevance to the Conservation of New Zealand Stag Beetles

New Zealand Journal of Zoology, Volume 53, Issue 2, June 2026.
Insects use sensilla to detect chemical and physical stimuli, mediating behaviours such as mate finding, foraging and mechanosensory responses. The distribution and density of sensilla can be examined using scanning electron microscopy. Investigating these structures can help elucidate rarely observed behaviours (e.g. mate finding and foraging).
